Methane production, or methanogenesis, is the only biochemical pathway for ATP generation in methanogens. All known methanogens belong exclusively to the domain Archaea, although some bacteria, plants, and animal cells are also known to produce methane. [1]
Methanogenesis can also be beneficially exploited, to treat organic waste, to produce useful compounds, and the methane can be collected and used as biogas, a fuel. [21] It is the primary pathway whereby most organic matter disposed of via landfill is broken down. [ 22 ]
Hydrogenotrophs belong to a group of organisms known as methanogens, organisms that carry out anaerobic processes that are responsible for the production of methane through carbon dioxide reduction. Methanogens also include a group of organisms called methylotrophs , organisms that can use single-carbon molecules or molecules with no carbon ...
Methanotrophs (sometimes called methanophiles) are prokaryotes that metabolize methane as their source of carbon and chemical energy.They are bacteria or archaea, can grow aerobically or anaerobically, and require single-carbon compounds to survive.
Biological methanation takes place in a separate methanation plant. The gas is completely converted into methane before the infeed into the gas grid. The carbon dioxide, produced in a gas processing system, is converted into methane in a separate methanation plant, by adding hydrogen and can then be fed into the gas grid.
Solid-state anaerobic digestion, which contains six genera of methanogens including Methanobacteria, can ferment rice straw and then produce methane. Since conventional treatment is burning rice straw in field, applying Methanobacteria to waste disposal process can reduce the air pollution caused by straw burning and also alleviate energy ...
Methanosarcina barkeri is the type species of the genus Methanosarcina, characterized by its wide range of substrates used in methanogenesis.While most known methanogens produce methane from H 2 and CO 2, M. barkeri can also dismutate methylated compounds such as methanol or methylamines, oxidize acetate, and reduce methylated compounds with H 2.
Euryarchaeota (from Ancient Greek εὐρύς eurús, "broad, wide") is a kingdom of archaea. [3] Euryarchaeota are highly diverse and include methanogens, which produce methane and are often found in intestines; halobacteria, which survive extreme concentrations of salt; and some extremely thermophilic aerobes and anaerobes, which generally live at temperatures between 41 and 122 °C.
